To prepare spray solution, drop the unopened packet(s) of Orthene Turf, Tree & Ornamental WSP into a spray tank containing at least one half the total quantity of water required. Direct water at the floating packet(s) and continue to add water with the agitator running until the spray volume is reached. Do not add any liquid fertilizers, micronutrients or adjuvants to the spray solution until after the packet and its contents have completely dissolved. Water soluble packet(s) should completely dissolve in approximately five minutes. Dissolution rate may be slowed by cold water, lack of agitation or water containing high concentrations of boron or sulfur.


A variety of factors including weather conditions, (e.g., wind direction, wind speed, temperature, relative humidity) and method of application (e.g., ground, aerial, airblast) can influence pesticide drift. The applicator and grower must evaluate all factors and make appropriate adjustments when applying this product.

Refer to the Tables of Equivalents to calculate the number of packets to use. (See label)

  • All aerial, ground and air-assisted/airblast application equipment must be properly maintained and calibrated using water as carrier. Do not apply this product as an ultralow (ULV) spray, or in any carrier other than water.
  • Use the largest droplet size consistent with good pest control. Small droplets are more prone to spray drift and can be minimized by appropriate nozzle selection, by orienting nozzles away from the air stream as much as possible, and by avoiding excessive spray boom pressure.
  • Do not apply at wind speeds greater than 10 mph at the application site.
  • Make applications when wind velocity favors on-target product deposition (approximately 3 to 10 mph).
  • Apply as close to target plants as practical to obtain a good spray pattern for adequate coverage.
  • For aerial applications, do not apply at heights greater than 10 feet (consistent with flight safety).
  • For airblast applications, direct spray above foliage and turn off outward pointing nozzles at row ends and outer rows.
  • For aerial applications, the spray boom should be mounted on the aircraft so as to minimize drift caused by wing tip vortices. The minimum practical boom length should be used and must not exceed 75% of wing span or rotor diameter.
  • For ground applications, do not apply at heights greater than 4 feet.

    If you have sucking pests on a non food plant, Orthene is taken up thru the whole plant. When the pests eat the leaf they get a dose and die, pretty much lasts for 6 weeks. Works like a charm.
